NewsOptimal timing maximises Paxlovid benefits for treating COVID-19
Study suggests using the anti-COVID-19 treatment Paxlovid three to five days after symptoms emerge in patients and expanding global access to the drug may help reduce the severity and transmission of the SARS-CoV-2 virus.

NewsOdor-causing bacteria in armpits targeted using bacteriophage-derived lysin
Researchers analyzed bacterial metabolism and the DNA of skin microflora in armpit fluid samples and found odor-causing precursors along with a proliferation of Staphylococcus hominis bacteria.

NewsGut bacteria can change their ‘software’ in reaction to inflammation
New research reveals an ingenious adaptation strategy used by gut microbes, allowing them to dynamically reprogram gene expression based on local conditions like inflammation or viral attacks.

NewsRise seen in use of antibiotics for conditions they can’t treat – including COVID-19
A five-year trend study shows a rebound in inappropriate use after an early-pandemic dip, and a need to tackle overuse in all patients during viral illness outbreaks.

NewsBlack women hospitalised in USA with blood infection resistant to last-resort antibiotic at increased risk of death
New research finds that the odds of death in black women with a bloodstream infection (BSI) caused by carbapenem-resistant enterobacterales (CRE) was twice that of black men or white women.

NewsLongest known SARS-CoV-2 infection of 613 days led to unique highly mutated variant
New research to be presented at next week’s ESCMID Global Congress highlights the risk of new immune-evasive SARS-CoV-2 variants emerging in immunocompromised patients.

NewsNanoparticle enhances antibacterial sonodynamic therapy for eradication of Pseudomonas aeruginosa biofilm
A novel ultrasound-launched targeted nanoparticle was developed to universally destroy biofilm, target bacteria, deliver antibiotics, and efficiently kill bacteria via ultrasonic cavitation and antibacterial sonodynamic therapy.

NewsResearchers resolve old mystery of how phages disarm pathogenic bacteria
Scientists observed how a phage called PP7 infects Pseudomonas aeruginosa by attaching to the pilus, which then retracts and pulls the phage to the cell surface.

NewsAntibiotics aren’t effective for most lower tract respiratory infections
Use of antibiotics provided no measurable impact on the severity or duration of coughs even if a bacterial infection was present, finds a large, prospective study of people who sought treatment for lower-respiratory tract infections.

NewsBiofilms play key role in reducing sensitivity to ionic silver in wound pathogens.
Bacterial pathogens in wounds that have been treated with ionic silver can adapt and become less sensitive - thanks to biofilm formation.

NewsStudy suggests antibiotic-resistant ‘superbugs’ are being passed from cats and dogs to their owners
Pet dogs and cats in Portugal and the UK were carrying the same antibiotic-resistant bacteria as their owners, highlighting the importance of including pet-owning households in surveillance programmes for antibiotic resistance.
